java.sql.Connection.setTransactionIsolation method

java.sql.Connection.TRANSACTION_SERIALIZABLE, java.sql.Connection.TRANSACTION_REPEATABLE_READ,
java.sql.Connection.TRANSACTION_READ_COMMITTED, and java.sql.Connection.TRANSACTION_READ_UNCOMMITTED transaction
isolations are available from a Derby database.

TRANSACTION_READ_COMMITTED is the default isolation level.

Changing the current isolation for the connection with setTransactionIsolation commits
the current transaction and begins a new transaction.
For more details about transaction isolation, see "Locking, concurrency, and
isolation" in the
Java DB Developer's Guide.
